| Abstract: | The geodynamic evolution, deep structure, and metallogenic regionalization of the Rudny Altai are considered in terms of plate tectonics. The base-metal massive sulfide deposits are genetically related to the group of basalt-andesite-rhyolite sequences formed in rift or island-arc geodynamic setting in the Devonian at the early stage of Hercynian tectogenesis. Taking into account economic reserves of ore and major metals (Cu, Pb, Zn, Au, Ag), as well as lateral and vertical regional metallogenic zoning of the Rudny Altai, the localization of massive sulfide mineralization in ore-bearing structural elements and particular deposits has been specified. The ore productivity of ore-bearing geochronological levels for base metals and the contribution of these levels to the total reserves of the region are characterized in detail. The Rudny Altai basemetal belt is regarded as a continuous ore-bearing structural unit situated in Russia and Kazakhstan. |
